METHOD OF SPOOLING BARBED WIRE l A 4 I 2 )n M Patented Aug. 10, 1937UNi'iED srsras METHOD SPOOLING BARBED WIRE George Lawson Brown, Preston,England Application May 4, 1935, Serial No. 19,884' In Great Britain May4, 1934 4 Claims. (01. -422) This invention relates to barbed wire andto a method of spooling it.

Generally, barbed wire is sold in spools wound upon a core or former andit is inconvenient to handle owing to the fact that a large number ofbarbs project out from the surface of the spool.

The present invention has for its object to provide a method of spoolingbarbed wire in a manner which will avoid outwardly projecting barbs..Moreover, the invention is concerned with forming the barbs in such away as to render it possible to spool barbed wire so that none of thebarbs project outwardly.

It will be appreciated that in the following description the wordspooled does not necessarily imply Wound on a spool or core, forobviously a material like barbed wire is suificiently stiff for acentral core to be dispensed with.

According to the present invention, barbed wire is spooled so that itsexposed convolutions present their barbs inwardly. Preferably, all theconvolutions present unbarbed surfaces outwardly, and in order toachieve this the barbs are provided in units along the wire, and inaccordance with the usual practice each barb unit may comprise one or aplurality of barbs, but where a plurality of barbs are provided, it isessential, according to the present invention, that they are arranged infan form and confined within an angle of subtended about the strand,although it will of course be obvious that the barbs are not necessarilyin the same plane longitudinally of the strands. It is convenient in themanufacture of barbed wire according to the invention to arrange thebarbs in fan form and contained within an angle of approximately 90subtended about the strand, and to spool the wire by flat coiling thestrands into a long helical coil, with all the barbs inside, whereafterthe long helical coil may be wound into a spool the axis of which is atright-angles to the axis of the long helical coil and substantiallyparallel with the major axis of the flat coils.

In order that the invention may be clearly understood and more readilycarried into effect, it is hereinafter described with reference to theaccompanying diagrammatic drawing, in which:

Figure 1 illustrates a short piece of barbed Wire formed according tothe present invention; while Figure 2 shows barbed wire spooled in amanner also according to the present invention.

It will be seen by reference to Figure 1 that the barbs 3 comprise ashort length of wire, which is wound about a strand 4 and has twoprojecting prongs. For the sake of convenience, it may be said that theprongs are arranged in fan form, the fan being confined within an angleof approximately 90 subtended about the strand 4, and it will be seenthat the fan extends from the wire in substantially the same directionradially of the wire.

Dealing now with Figure 2, it may be said that the barbed wire asdescribed with reference to Figure l is fiat coiled, as indicated at 5,into a long helical coil with the barbs all directed inwardly, asindicated at 3, that part of the long helical coil which has been drawnaway from the remainder of the spool being indicated in the drawing bythe reference numeral 6. The long helical coil 6 is then spooled bywinding in the manner shown, the axis of spooling being substantially atright-angles to the long axis of the helical coil 6 and substantiallyparallel with the major axes of the flat coils 5. Although in thearrangement shown all the barbs are directed inwardly, with the resultthat a smooth outer surface is presented which is free from outwardlyprojecting barbs, and although the wire preparatory to spooling in themanner above described had all the barb fans pointing in substantiallythe same direction radially of the strand, it will be observed that asthe strand is pulled substantially axially of the flat coils 5, theaction is first to turn the helices of each fiat coil through an angleof 90 in opposite direction so that they lie substantially in the sameplane and substantially at right-angles to their original plane; duringthis operation, however, no twisting moment is imparted, with the resultthat the barbs 3 will point in opposite directions, and in consequencewhen the wire is pulled taut adjacent fans of the barbs will be disposedmore or less at right-angles to one another, as indicated in thestretched out end piece of wire by those barbs indicated with thereference numerals 3a and 3b.

It is convenient to spool the wire upon a core l, and for carryingpurposes there is provided a stirrup or carrying frame 8, the crosspiece 9 between the two arms serving as a handle. Intermediate thehandle and the periphery of the spool there may also be provided thesliding member Ill, which may be pressed down to bear tightly againstthe periphery of the spool and prevent unwinding.

It will be appreciated that the invention so far as it concerns themethod of coiling the barbed wire may be applied to all forms of wire,but where the wire is of such form that it is not naturally adapted tohave the barbs directed infaces, which consists in flat coiling thestrands.

2. The method of spooling barbed wire wound upon a core so that itsexposed convolutions present unbarbed surfaces by flat coiling thestrands into a long helical coil with the barbs presented inwardly, andwinding the long helical coil into a spool the axis of which is atright-angles to the axis of the long helical coil, and fitting acarrying frame to the spool.

3. The method of spooling barbed wire which consists in flat coiling thestrands into a long helical coil with its barbs presented inwardly byforming each barb unit as a single barb, adjacent barbs subtending anangle of less than one hundred and eighty degrees on the same side ofthe strand, and winding the long helical coil into a spool.
